KDS-7XII Radio Remote Control System   

-4-

 

2. Connect Devices to Receiver 

Connect all devices and parts to the corresponding channels. Take notice of 3P signal wire must be 

connected in right way. Otherwise, it will cause the severe damage to certain device or fail to work. 

There are some corresponding symbols of 3P on one side of the receiver: 

(-)

    means cathode of power connected to the earth, usually links to the black line or brown 

line of 3P signal wire 

(+)   

means the anode of power, usually links to the red wire of 3P signal wires. 

(s)   

means signal wire, usually links to the white or yellow wire of 3P signal wires. 

 

Notice:  please  assess  the  power  demand  of  the  receiver  of  model  when  selecting  the  electricity 

supply  style,  ensure  the  receiver  can  get  enough  power  supply  when  using,  the  voltage  of  the 

receiver not less than 4.2V at any time. 

3. Binding Transmitter and Receiver 

Before  using  K-7XII,  you  must bind  the  transmitter  and the  receiver.  Binding  them  as following 

steps: 

1)

 

Plug the 'BIND line' into the 'BIND' slot of receiver. Then power on receiver by plugging the 

ESC line, then the LED of receiver will flash fast. Then you can remove the 'BIND line'. 

2)

 

Hold  'ESC'  button  of  transmitter,  then  turn  on  it  (keep  holding),  the  LCD  will  display  as 

following. 

 

3)

 

After few seconds, binding will finish, the LED of receiver will shine three times slowly, and 

then the transmitter enters working mode. 

4)

 

  Release 'ESC' button of transmitter, it will enter working mode. 

Notice:   

1)

 

K-7XII  supports  multiple  receivers  operation  and  long-distance  binding,  so  please  make  sure 

only  you  bind  the  radio  at  that  time.  If  there  is  any  person  who  also  uses  KDS-7XII  2.4GHz 

remote controller system locally, please operates only after other users pare the signal. 

2)

 

K-7XII  supports seven  models saving in  one transmitter. They  are numbering as M/1 to M/7. 

The  binding  will save the serial numbers in receiver. So if you  bind  one receiver with M/1, it 

can only work when the transmitter is switched to M/1. 

4. Control Distance 

All radio control system equipment has an effective control range. It’s not the same on the ground, 

water surface or flying in the sky; It is not the same on flat ground or complicated layout; It’s not
